A vulnerability in the Traversal Using Relay NAT (TURN) server included with Cisco Meeting Server (CMS) could allow an authenticated, remote attacker to gain unauthenticated or unauthorized access to components of or sensitive information in an affected system. The vulnerability is due to an incorrect default configuration of the TURN server, which could expose internal interfaces and ports on the external interface of an affected system. An attacker could exploit this vulnerability by using a TURN server to perform an unauthorized connection to a Call Bridge, a Web Bridge, or a database cluster in an affected system, depending on the deployment model and CMS services in use. A successful exploit could allow the attacker to gain unauthenticated access to a Call Bridge or database cluster in an affected system or gain unauthorized access to sensitive meeting information in an affected system. To exploit this vulnerability, the attacker must have valid credentials for the TURN server of the affected system. This vulnerability affects Cisco Meeting Server (CMS) deployments that are running a CMS Software release prior to Release 2.0.16, 2.1.11, or 2.2.6. Cisco Bug IDs: CSCvf51127.

Security readout for executives and security teams

Cisco Meeting Server deployments with the affected TURN server configuration could expose internal meeting-system services through an external interface. An attacker with valid TURN credentials could reach components that should not be externally accessible and may access sensitive meeting information or system components. Exposure is likely limited to Cisco Meeting Server deployments running vulnerable releases with TURN enabled and externally reachable. Impact depends on which CMS services are deployed behind the TURN server and whether valid TURN credentials can be obtained or abused. Prioritize remediation for internet-facing CMS deployments because the issue can expose sensitive meeting data or internal CMS components. The urgency is lower where TURN is not externally reachable or the platform is already on fixed releases. Mitigation focus: Upgrade CMS to 2.0.16, 2.1.11, 2.2.6, or later as applicable.; Review Cisco advisory cisco-sa-20170913-cmsturn for official remediation guidance.; Restrict TURN server access to intended users and networks where operationally possible..
